Have you ever visited the WordPress editor and noticed the “welcome” popup, despite dismissing it ages ago? Or, logged in with a new browser only to reconfigure settings, such as enabling top toolbar support and turning off fullscreen mode? Annoying, right?

This has been a long-standing issue caused by WordPress storing user preferences in the browser. In Gutenberg 13.2, these preferences are now saved as user metadata in the database and should no longer pose an issue.
